[Update 9/14/2016: The previous version of this announcement indicated that you would be unable to create experiments starting on October 17, 2016. After hearing your feedback, we have decided to continue to allow full ExperimentService functionality in existing API versions up until the final shutoff date.]

As a result of this expanded functionality, the ExperimentService will be sunset. If you’re still using the ExperimentService, please take the time to update your code to use campaign drafts and experiments instead.

On February 1, 2017, all experiments running via the ExperimentService will be stopped. After this date, all ExperimentService experiments will be deleted, stats will be unavailable, and API calls to the ExperimentService across all API versions will result in an error.

Please move off the ExperimentService before February 1, 2017 to ensure that you are able to continue running experiments.
